java.util.Locale making Country LowerCase

问题

I am setting

java.util.Locale localeWithoutCountryCode = new Locale("fr_FR");

But when I retrieve its value, it returns me "fr_fr" ( Lowercase country) and this is causing my message lookups to fail. I want it to keep the country case as is.

回答1:

The single-argument constructor for Locale takes exactly an ISO language as its parameter; you're passing in a language and variant. Use new Locale("fr", "FR") instead.

If this is hard-coded for some reason, you can just use Locale.FRANCE.
